Abstract
EN CONOCIDOS REGENERADORES, QUE CUMPLEN LA RECOMENDACION CCITT G.958, SE SUPERVISAN SECCIONES DEL REGENERADOR POR LA SUPERVISION DE LA PROBABILIDAD DE ERROR DE TRANSMISION DE SEÑALES SDH (JERARQUIA SINCRONA DIGITAL) MEDIANTE LA DETERMINACION DE LA PARIDAD. ESTO EXIGE EL DESARME Y RESTABLECIMIENTO DE LA SEÑAL SDH. PARA ELLO, SON NECESARIOS DISPOSITIVOS DE PROCESAMIENTO DE SEÑALES ESPECIALES NO NECESARIOS COMO TALES PARA LA REGENERACION DE LAS SEÑALES DE TRANSMISION, COMO MULTIPLEXOR Y DEMULTIPLEXOR, QUE ORIGINAN UNA CONSIDERABLE POTENCIA DE PERDIDA. EN EL REGENERADOR DE LA INVENCION (RE) TIENE LUGAR LA DETERMINACION DE LA PROBABILIDAD DE ERROR DE TRANSMISION MEDIANTE LA COMPARACION DE UNA PALABRA CONOCIDA EN LA PARTE DE CABECERA DE UNA SEÑAL STM-N CON UNA PALABRA DE REFERENCIA. A PARTIR DEL RESULTADO DE LA COMPARACION SE DERIVA LA PROBABILIDAD DE ERROR DE TRANSMISION Y SE TRANSMITE A UNA CENTRAL A TRAVES DE UNA LINEA DE ERRORES (FL). PARA LA TRANSMISION DE LA PROBABILIDAD DE ERROR DE TRANSMISION EN UNA SEÑAL STM-N, LA PROBABILIDAD DE ERROR DE TRANSMISION PUEDE TENER LUGAR A TRAVES DE UN REGENERADOR QUE CUMPLA LA RECOMENDACION CCITT G.958, BAJO LA UTILIZACION DE P.EJ. EL CANAL DE SERVICIO.
